Chapter 12

Q. 12.18

A variable-frequency sinusoidal voltage source is connected to the circuit in Fig. 12.11. The rms amplitude of the source is held at  10 V  and the rms amplitude of the current entering the circuit is observed as the frequency of the source is varied from 1 to 500  kHz . What is the ratio of the rms current at 50  kHz to that at  300 kHz?

Step-by-Step

Verified Solution

The impedance equals  40 dB  at 300  kHz  and  20 dB  at  50 kHz , so the impedance at  300 kHz   is 20 dB  above or ten times that at 50  kHz . Thus the rms current at  50 kHz  is ten times that at  300 kHz .
